We have already seen OpenDNS, a free DNS service which is fast and reliable and here is another name which speaks of reliability….Yes its Google.

Google’s DNS servers claim that they resolve DNS queries quicker to provide a faster browsing experience.

Google has introduced a free DNS service, but it does not provide any customization and filtering as OpenDNS does.

The IP addresses of Google DNS Servers are:

Primary DNS    8.8.8.8
Secondary DNS    8.8.4.4

Some people confuse it with Level3 DNS servers because the IP range of Google’s DNS servers fall within the IP address rangle allocated to Level3 Communications.

But Google runs its servers themselves and says that users will be protected by DoS Attacks (Denial of Service) which sometimes happen through DNS servers. Also Google claims that the servers are fast and are located at many places around the world which provides fast access to users in many countries.

I must remind you that changing your DNS servers DOES NOT MEAN faster DOWNLOAD SPEEDS.

If you want to use Google DNS servers, simply point your connections Primary and secondary DNS servers to the one which have been given above.

A detailed guide is given in my earlier post on how to use OpenDNS servers for better browsing experience.

A short article on Torrents: Written By TuX (Site Admin)

We all have been witnessing the rise of the content distribution network – The Torrent.

It is a P2P sharing technology which enables users to share files with other users.

There are some things you need to know about before you can actually utilise the torrent network….

Seed is a user/computer which is allowing other users to download the file from it and it has finished downloading the file.

Peer is a user/computer which is downloading the file from other seeds/peers.

1. Torrent Files (.torrent extension)
2. Torrent Client (a program which can download files supporting the .torrent extension)
3. Torrent Tracker

Now we will explain you point by point so that you know about the background of the P2P network….

1. Torrent Files – The torrent files can be downloaded from many distribution sites such as bittorrent.com or ubuntu.org

(which provides ubuntu Operating System)

You can download .torrent files which are necessary to download the files. These files are small in size and some people

confuse them being actual files. So download .torrent files and keep it on your computer at a know location (e.g. Desktop)

2. Torrent Client – Many popular torrent clients are on the Internet.

The most popular are uTorrent and Azureus. uTorrent is a very lightweight client (download size is only 180KB) and uTorrent

offers good functionality and ease-of-use.

Azureus is for the power user and it offers a lot of tweaks and now comes with a new interface called Vuze which is like an

online media library which allows the users to watch or download videos and movies.

Both the torrent clients are free and the download links are provided at the end of article.

Many download managers and third party programs also have torrent file downloading capabilites but we recommend you to use

dedicated torrent downloader like the two listed above.

3. Torrent Tracker – This is the most confused concept amongst the torrent users who are currently using torrents.

A torrent tracker is a server which contains the addresses of the seeds/peers which are sharing a particular torrrent.

The tracker keeps a ‘track’ of the users which share the torrents. There are many torrent trackers on the internet. Some

trackers are provided by:

openbittorrent.com
publicbt.com

There are numerous other trackers and it is recommended to add more trackers so as to discover more peers as peers use many

different trackers.

Here is a screen-shot of uTorrent:

Sun xVM VirtualBox is a freeware from Sun Microsystems, the creators of Java, Solaris and many other great open source products.

Sun xVM VirtualBox is a software which allows users to install multiple virtual operating systems on their computer which do not affect your current system configuration.

Virtual operating systems do not affect the system in any way, as the virtual operating system creates a seperate
area in which operating systems can be installed. The operating system which is installed as Virtual OS does not
know that it is being installed on a “Virtual Machine” instead of an “Actual Machine or Host Machine”.

I have installed Sun VirtualBox on my system and loaded Ubuntu 9.10 on my laptop….Look at the screen-shot below.

VirtualBox Main Screen

Installing an Virtual Operating System is very easy. You have to first create a Virtual Machine by Clicking on the New Button. You have to adjust the amount of Hard-Disk space and the RAM to be allocated to the machine.

You have to create the Virtual Machine and prefer the Dynamically Expanding Storage as it expands only when the space is used up by the operating system. (Though I have observed that it causes a lot of fragmentation of the file in which the Virtual OS is installed). You should allocate atleast 8GB HDD space for Linux operating system and more if you want to install an operating system like Windows Vista.

VirtualBox also allows the user to use the internet if available on the host operating system. The software creates a VirtualBox Host-Only network which allows the sharing of internet.

You can also use your removable drives (USB drives) and you can also use shared folders to share files from the host machine.

I have installed the Ubuntu OS which has Firefox installed and I have used it to surf the internet without any settings or any procedure on the Virtual Operating System. If you have internet running on the host machine then you can directly use the internet on the Virtual OS.
